Spaces are deleted in some field data in standard output

When running this command:
./target/release/hayabusa csv-timeline -d ../hayabusa-sample-evtx -r ../hayabusa-rules/hayabusa/builtin/PowerShellClassic/PwShClassic_400_Info_PwShEngineStarted.yml
with this new rule:

title: 'PwSh Engine Started'
description: 'Engine state is changed from None to Available.'

when I output to CSV: -o test-400.csv and check the results there are spaces just like the original log:
Example

However, the standard output shows this:

I want to keep spaces between CommandName=, CommandType=, etc...
